Abdominal bloating with indigestion may be caused by stomach cancer, but it is not necessarily stomach cancer, it may also be the symptom of some benign diseases. Early stage patients of stomach cancer usually have no obvious specific symptoms, and can have some non-specific digestive symptoms, such as abdominal bloating, epigastric discomfort or hidden pain, nausea and vomiting, lack of appetite, dyspepsia and so on. If patients also have symptoms such as obvious weight loss, anemia, fatigue, obvious pain in the upper abdomen, enlarged left subclavian lymph nodes, etc., they should suspect the possibility of gastric cancer. At this time, the patient should go to the hospital as soon as possible to find a specialized doctor to improve the relevant examination and symptomatic treatment. Besides gastric cancer, many benign gastric diseases can also show symptoms of bloating with indigestion, such as chronic gastritis, gastric ulcer, functional dyspepsia, irritable bowel syndrome and so on. When bloating and indigestion occur, it is recommended to go to the hospital as soon as possible to improve relevant examinations, such as gastroscopy, so as to clarify the cause of the disease and provide targeted treatment as soon as possible.
